Overview
The ADS8598SIPM is an 8-channel, integrated data acquisition (DAQ) system developed by Texas Instruments. This device is based on an 18-bit successive approximation (SAR) analog-to-digital converter (ADC) and features a complete analog front-end (AFE) for each channel. It supports simultaneous sampling of all input channels, achieving a maximum throughput of 200 kSPS per channel. The ADS8598SIPM is designed for high-performance applications, offering zero-latency conversions and a flexible digital interface that supports serial, parallel, and parallel byte communication.
